Introduction
Johns Hopkins University is concerned about the safety and welfare
of its faculty, staff and students. We are committed to alerting
individuals to potential work-related health risks and counseling
them on methods to avoid workplace hazards through a comprehensive
occupational health and safety program.
Safety Responsibilities
Individuals
All faculty, staff, students and fellows are responsible for compliance
with appropriate safety and health standards as issued by Johns
Hopkins. Faculty, staff, students and fellows are to follow safe
work practices and report all unsafe conditions.
Faculty and Supervisors
Faculty and supervisors and faculty are the keystone of the Johns
Hopkins University Safety Program. Faculty and supervisors train
employees, fellows and students to develop and maintain safe work
practices. Faculty and supervisors must frequently inspect the workplace
to ascertain unsafe conditions. Faculty and supervisors should be
aware that Johns Hopkins University has policies addressing disciplinary
action for failure to comply with safety policies. Principal investigators
are responsible for ensuring that all individuals working under
their supervision have a safe working environment and are educated
of the potential hazards associated with their jobs.
Health, Safety and Environment
The Department of Health, Safety and Environment is responsible
for providing guidance and direction in all phases of the Johns
Hopkins Safety Program. Health, Safety and Environment conducts
safety inspections, and advises management of unsafe conditions
or noncompliance with policy, regulations and standards. Health,
Safety and Environment reports all of its activities to the Joint
Committee for Health, Safety and Environment.
Joint Committee on Health, Safety and Environment
The Joint Committee on Health, Safety and Environment was established
by the President of The Johns Hopkins University and the President
of The Johns Hopkins Hospital to develop and enforce policies related
to health, safety and the environment, and to ensure compliance
with all applicable safety and environmental regulations. The Chairman
of the Joint Committee on Health, Safety and Environment is Edward
J. Bernacki, MD, MPH. The Joint Committee on Health, Safety and
Environment collaborates with the Animal Care and Use Committee
to assure safety of individuals involved in the care and use of
animals.

Animal Exposure Surveillance Program
All individuals (faculty, staff, fellows and students) who have
direct contact with animals, living tissues, body fluids, wastes
or living quarters are required to participate in the Animal Exposure
Surveillance Program (AESP). This program is managed by the Occupational
Health Services,Church Home Hospital, 98 N. Broadway, Room 421 (phone
410-955-6211). The AESP allows Johns Hopkins University to monitor
your level of risk in handling animals, offer you appropriate prophylactic
protection from diseases associated with animal handling, assess
your current health status, and monitor your health during employment
or training at Johns Hopkins University.
People with impaired immune function may be at increased risk from
hazards associated with animal care and use. Moreover, a large number
of workplace chemicals, physical and biologic agents can damage
the reproductive systems of both male and female workers, resulting
in infertility, spontaneous abortion, developmental impairment or
death in an embryo, fetus or child. These risks are discussed during
AESP enrollment.
Identification and registration
of individuals at risk
- Principal investigators and departmental administrators are
responsible for forwarding the names of postdoctoral fellows
and students with significant animal contact to Occupational
Health Services. Human Resources will identify other staff during
pre-employment screening.
- Occupational Health Services conducts pre-employment medical
examination and risk assessment for all staff.
- Education
- Pre-employment orientation

Hazards associated with working
with animals
- Physical e.g. steam, bites, scratches, kicks, sharps, noise,
ergonomic hazards, wet floors, electricity, and radiation
- Biological e.g. viruses, parasites, bacteria, rickettsiae,
fungi which can be transmitted between animals and humans (zoonotic
agents)
- Chemical e.g. cleaning agents, anesthetics, laboratory chemicals:
which may be flammable, explosive, corrosive, irritating or
toxic. Always check Material Safety Data Sheets.
- Occupational Health and Safety in the Care and Use of Research
Animals., (1997) Institute of Laboratory Animal Research, National
Research Council and Biosafety in Microbiological and Biomedical
Laboratories, (1999) Public Health Service/CDC/NIH provide extensive
information and references.
Hazardous materials require approval by the Health, Safety and
Environmental Health (410-955-5918) before use in animal facilities.
See the Johns Hopkins Safety Manual for general information. Investigators
using biohazards or radioactive materials should advise the Facility
Manager and animal caretakers on the appropriate way to handle and
dispose of animals, tissues, carcasses and bedding contaminated
by these materials.

Laboratory Animal Allergies
Allergic reactions to animals are among the most common conditions
that adversely affect the health of people working with animals
in research. Over 40% of people routinely working with animals
develop allergic symptoms. More than 70% of people with pre-existing
allergic disease eventually develop allergy to laboratory animals
over a period of 1-2 years, most commonly manifested as rhinitis,
itchy eyes, and rashes. An estimated 10% of laboratory workers
eventually develop occupationally related asthma, and related
symptoms of coughing, wheezing, and shortness of breath, which
can persist for months or years after exposure ceases.
Rats, mice, guinea pigs, rabbits and cats are probably among
the most important inducers of allergies in laboratory animal
workers. Allergens present in the urine, saliva, fur, dander,
bedding and other unknown sources are aerosolized during handling
of the animals, clipping hair, cage changing, dumping bedding
and cleaning the animal rooms. Personal protective equipment such
as laboratory coats, gloves, face masks, respiratory equipment,
biosafety cabinets and dump stations reduce the risk of developing
allergies. Individuals who are already sensitized for example
due to allergies to domestic cats are in the highest risk category.
Laboratory animal workers should under go screening to identify
those at risk and participate in the monitoring program. If you
develop symptoms of job related animal allergies contact Occupational
Health Services at 410-955-6211.
Allergies are an important risk associated with animals. If you
feel you may suffer from an allergy to the animals you work with,
report to your supervisor and to the Occupational Health Services
for your campus to obtain appropriate treatment. Allergy can usually
be managed by a combination of medical management and workplace
strategies. It's important to consult with Occupational Health
Services to determine the cause of your allergy in order to manage
it effectively.
The following practices may help reduce your exposure to animal
allergens:
- When possible, perform animal manipulations in a ventilated
hood or a biosafety cabinet. If this is not possible, a dust mask
or surgical mask may be helpful.
- When you're not working in a hood or cabinet, make sure that
the animal room or other work area is adequately ventilated and
that all the air handling equipment in the room is in good order.
If there is doubt, your supervisor can ask Facilities to measure
the number of air changes in the room. Animal rooms should deliver
at least 10 air changes per hour.
- Don't wear your street clothes when working with animals. Wear
protective clothing.
- Reduce your skin contact with animals by wearing gloves and
long-sleeved lab coats.
- Wash your hands frequently. Wash hands, face and neck before
leaving the work area.
- Avoid touching your hands to your face while working with animals
and animal equipment.
- Keep cages and your work area clean.
Physical Hazards
- Bites and Scratches
All animals are capable of inflicting bites and scratches. Small
animals, such as rodents and rabbits usually deliver relatively
minor wounds. Larger species like cats, dogs and nonhuman primates
can inflict severe wounds. Bite and scratch wounds can become
infected by the normal bacterial flora of the animal's mouth
or toenails, or by bacterial flora from the individual's skin.
To prevent bites and scratches use the proper animal handling
techniques. Protective garments, such as gloves, gauntlets and
long-sleeved laboratory coats limit injury to the hands and
arms. Contact Comparative Medicine (410-955-3273) for guidance
on appropriate animal handling and restraining devices. In case
of a bite or scratch immediately wash the wound with plenty
of soap and water, contact your supervisor and proceed to the
Occupational Injury Clinic (410-955-6433). If, you are bitten
or scratched by a cat, dog, nonhuman primate or wild animal
notify Animal Services (410-955-3713) so appropriate veterinary
follow-up measures diagnostic procedures can be performed on
the animal.
- Splashes
In case of a splash or exposure to potentially infectious material
involving your eyes, nose or mouth, flush the site with water
for fifteen minutes, and proceed to the Occupational Injury
Clinic for your campus.
- Musculoskeletal disorders
Musculoskeletal disorders are syndromes characterized by discomfort,
impairment, disability or persistent pain in joints, muscle
tendons or other soft tissues with or without physical manifestations.
If you experience any of these conditions while performing your
job, please report to the Occupational Injury Clinic for your
campus. If you would like a proactive ergonomic assessment of
your work site, ask your supervisor to contact the Department
of Health, Safety and Environment.
- Wet floors
Wet floors are a prominent physical hazard in animal areas.
Do your part in promptly reporting or eliminating wet floor
surfaces. If it is necessary to walk across wet floors, use
extreme caution. Proper non-slip shoes or protective boots are
recommended for environments that consistently have wet floor
surfaces. When possible, post wet floor signs to alert coworkers
and visitors of this hazard.
- High Pressure Water and Steam
High Pressure Water and Steam are physical hazards for animal
handlers who utilize autoclaves, power washers and other equipment.
Avoid skin contact with high-pressure water and steam. When
unloading an autoclave, verify that the pressure is near zero
prior to opening the door. Slowly crack open the door and allow
the steam to gradually escape. Allow materials in the autoclave
to cool for 10 minutes prior to removal and use heat resistant
gloves as necessary.
- Electricity
Electricity is an important physical hazard in the care and
use of animals. Johns Hopkins University Policy prohibits use
of extension cords, unless an emergency situation is declared
by administration. Use caution with power equipment, radios
and other electrical devices, particularly in areas with wet
floors, and water or steam sources.
- Radioactive Materials
All individuals using radioactive materials and/or animals containing
radioactive materials must be registered with the appropriate
Radiation Control Unit for your campus (East Baltimore Campus,
410-955-3712; Bayview Campus, 410-550-2423; Homewood Campus,
410-516-7308). The following guidelines should be adhered to:
- Animal handlers must wear gloves when handling a cage
or animal marked as radioactive.
- Cages containing radioactive animals must be labeled with
a "caution", "radioactive materials"
label. If the exposure rates outside the cage exceed 2 millirem/hour,
the cage must be shielded or moved to an area so that staff
will not be exposed to a radiation level above 2 millirem/hr.
- It is the responsibility of the researcher to collect
any material from the animal or cage (e.g., bedding, waste,
etc.) that may be contaminated, and place these materials
in a radioactive materials drum.
- East Baltimore Campus
- It is the responsibility of the researcher to monitor
the cage and associated equipment for radioactive contamination,
and to clean all contamination before the cage and associated
equipment is returned to Animal Services.
- Any radioactive animal carcass with a completed disposal
tag should be taken to the cold room in the Ross penthouse
and placed in the yellow barrels.
- Bayview Campus
- Researchers must have an approved disposal plan for radioactive
animal carcasses before radioactive material use. Radioactive
animal carcasses cannot be transported to the East Baltimore
Campus.
- Homewood Campus
- All experiments involving use of radioactive materials
in animals must first be approved by the Radiation Safety
Officer.
- Cages must be clearly and appropriately labeled with at
least identification of the radionuclide, total activity,
date and investigator.
- Only laboratory personnel trained by an authorized user
are permitted to handle radioactively labeled animals.
- Laboratory personnel and not animal caretakers are responsible
for handling contaminated bedding and animal waste, surveys
and decontaminating cages and equipment.
- Facilities can not be turned over to Animal Resources
for cleaning until certified free of removable contamination.
- Radioactive animal waste and bedding must be disposed
in special drums maintained by the Radiation Safety Office.
In no case will radioactive waste be transferred to the
regular animal facility trash. Regular animal facility caretakers
are not permitted to handle radioactive materials.
- Radioactive animal carcasses and bulk radioactive tissues
require special storage and ultimate disposal by a licensed
vendor. Contact the radiation safety office to make arrangements.
Biological Hazards
Common exposure routes for infectious agents are inhalation of
aerosolized agents, splash of infectious materials to the skin
or mucous membranes, or exposure via needle sticks, cuts and other
sharps injuries.
Any exposure to potentially infectious materials should be reported
via the incident reporting protocol previously outlined. Exposure
to the mucous membranes should receive on-site first aid by flushing
with copious amounts of running water. Exposure to the skin should
receive on-site first aid by washing the affected area with soap
and water. After on-site first aid, proceed to the Occupational
Injury Clinic for your campus:
- East Baltimore Campus, Blalock 139
- Bayview Campus, Asthma and Allergy Center, Room 2B.34
- Homewood Campus, Employees, Wyman Park Bldg., 6th floor and
Students, AMR II, Student Health Services
Blood borne Pathogens
Johns Hopkins University Blood borne pathogen exposure control
policy requires prompt reporting of exposure to human blood
borne pathogens. Call 410-955-STIX to report exposures. The
Johns Hopkins STIX Hotline is a 24-hour hotline staffed by an
infectious disease specialist. If your exposure is high risk
for blood borne pathogen infection, post exposure prophylaxis
may be recommended. These medications have been shown to be
effective in reducing the risk of HIV infection if initiated
within 1-2 hours of exposure.
All faculty and staff with exposure to human blood borne pathogens
will be entered in the Johns Hopkins University Blood borne
Pathogen Exposure Control Program upon hire or upon initiating
work with blood borne pathogen containing materials. All persons
entered in this Program are offered the hepatitis B vaccination
at no charge. The vaccination is obtained from the Occupational
Health Services for your campus.
The basis of Standard Precautions is to treat all human specimens
and primate specimens as infectious. Also treat all human subjects
and non-human primates as infectious.
The highest risk of infection from blood borne pathogens occurs
from needles and sharps. Sharps are defined as any item that
can puncture human skin or a red trash bag. Needles and sharps
are never to be discarded directly into the general waste stream
or red trash bags. All needles and sharps must be discarded
directly into approved sharps containers. Approved sharps containers
must be placed in all areas where sharps may be utilized or
generated. Filled sharps containers must be properly secured
prior to disposal, and are disposed in red bags or biohazard
boxes lined with red bags, as appropriate for your building.
- Hand washing
Hand washing is the most effective way to prevent infections to
you and coworkers. All animal areas should be equipped with a
hand sink that is stocked with liquid soap and paper towels. Wash
your hands often, using soap and water.
All infectious materials and all contaminated equipment or apparatus
should be decontaminated before being washed, stored or discarded.
Autoclaving is the preferred method for decontamination and disinfection.
All areas and equipment involving any contact with sheep or goats
or products of conception from sheep or goats shall be cleaned
and disinfected on a regular basis and immediately after each
operation. Transport carts shall be decontaminated after use.
The containment of infectious agents is performed according to
the applicable Biosafety level. Biosafety Level I generally involves
agents of no known or minimal potential hazard to laboratory personnel
and the environment. Biosafety Level II includes all Biosafety
Level I practices plus partial containment equipment such as biological
safety cabinets, protective barriers such as lab coats, gloves,
and face protection, and limited access to the laboratory. Work
involves agents of moderate potential hazard to personnel and
the environment. Biosafety Level III is designated for research
utilizing indigenous or exotic agents that may cause serious or
potentially lethal disease as a result of exposure by the aerosol
route.
Zoonotic Diseases
Zoonotic diseases are those diseases of animals capable of infecting
humans. A number of zoonotic diseases are of potential hazard
in institutions conducting animal based research. Such diseases
are rare in rodents, rabbits, cats and dogs raised indoors for
research purposes. There is a higher possibility of contracting
a zoonotic disease from random source cats, dogs, farm animals,
nonhuman primates and animals obtained from the wild (e.g. wild
rats, prairie dogs, woodchucks).
Humans may also become infected with agents introduced into animals
for research purposes. All such biohazardous research must be
registered with Health, Safety and Environment. You mist be instructed
by your employer in how to handle animals so infected. In case
of injury or unexplained illness associated with such animal use,
inform the medical personnel treating you of the possibility of
infection with that agent.
- Toxoplasmosis
Toxoplasmosis is caused by a protozoan parasite, Toxoplasma gondii.
The potentially infective form of the parasite (oocyst) occurs
in the feces of infected cats, however, indoor raised laboratory
cats may not be infected with this T. gondii. It takes 2 to 5
days after the feces are passed for the oocyst to become infectious.
Other animals, including man (and cats), become infected by eating
material contaminated by infected cat feces, or by eating raw
or improperly cooked tissue from other infected animals.
Usually this disease is quite mild and may be mistaken for a
simple cold. There may be a slight fever, mild headaches, general
tiredness and enlarged lymph nodes. Rarely heart, pulmonary or
liver disease, blindness or damage to the nervous system may occur.
Individuals with a compromised immune system may develop serious
illness. Transmission of the infection from a pregnant mother
to her fetus sometimes results in severe birth defects, stillbirth
and miscarriage.
Toxoplasmosis is easily prevented by avoiding exposure: effective
pest and vermin control programs, gloves, masks, protective clothing,
hand washing and do not eat, drink or apply make-up in animal
areas. Pregnant women should avoid working with cats, especially
handling cat litter or changing litter boxes. There is no vaccine
to protect humans from this parasite.
- Rabies
Rabies is a relatively rare and devastating viral disease, which
can result in severe neurologic problems and death. Most cases
of rabies occur in wild animals although any mammal can contract
the disease. Rabies is usually transmitted from infected mammals
(rabid cats, dogs or wild animals) to humans through bite wounds.
Rarely, infection may occur if a scratch or abrasion is contaminated
with saliva from an infected animal. Injuries sustained during
endotracheal tube insertion should be treated as though it were
a bite. Infected animals may shed the virus in saliva before the
visible signs of illness appear and that the virus can remain
viable in frozen tissues for an extended period. Aerosol transmission
is considered unlikely. Contact with bedding, cages or feed and
water bowls does not constitute an exposure. Purpose bred dogs
and cats raised indoors for research purposes by commercial suppliers
are not a risk for transmitting rabies because they are never
exposed to infected wild animals, and are usually vaccinated against
rabies.
The clinical signs shown by animals infected with rabies are
variable but may include: personality change for example a friendly
animal may appear to have become shy or it may be restless, excitable,
or aggressive; depraved appetite (animal eats strange objects);
change in vocalization, inability to eat or drink, and excessive
salivation due to by paralysis of the laryngeal muscles; and incoordination
or convulsions.
Following a bite, immediately wash the wound with plenty of soap
water and seek medical attention at the Occupational Injury Clinic.
In addition Animal Services (410-955-3713) should be notified.
The animal should be kept alive, quarantined and monitored by
veterinary staff for 10 days. If the animal was shedding rabies
virus at the time of the bite, it will die within 10 days. Alternatively,
the animal should be euthanized and the head submitted to the
Maryland State Health Department Laboratory for rabies evaluation.
A Rabies Prophylactic Vaccination Program is available to anyone
who works with potentially infected animals. Booster vaccinations
are done every three years.
- Tuberculosis
Tuberculosis is a chronic disease caused by bacteria in the genus
Mycobacterium. The disease is usually localized in the lungs but
other organs can also be affected. The main source of infection
for humans in the United States is other infected humans especially
in crowded conditions and in hospital settings. This disease is
highly infectious in a nonhuman primate colony often with a fatal
outcome. The most common source of infection for monkeys is from
infected humans or other monkeys.
For protection of the animals and individuals who work with them,
monkeys are routinely tuberculin tested. At six-month intervals
all individuals who work with nonhuman primates are notified of
the time and place for tuberculin testing. Wearing personal protective
equipment like facemask, gloves and laboratory coats when handling
or working with monkeys reduces the risk of exposure.
- Diarrheas associated with nonhuman primates
Nonhuman primates are potential sources of diarrhea-causing organisms
for humans. Animals may carry the organisms without showing signs
of disease. The most common diarrhea-producing organisms seen
in the nonhuman primates that are in this institution are Entamoeba
histolytica (the cause of amoebic dysentery), Shigella (the cause
of bacillary dysentery) and Campylobacter. Disease caused by these
organisms may be severe (diarrhea containing blood, mucus and
pus) or less severe with varying degrees of fever, abdominal cramps
and loose stools. If you develop diarrhea, inform the physician
treating you that you work with nonhuman primates.
Minimize chances of such infections by using personal protective
devices such as gloves, face masks and laboratory coats whenever
you are in contact with nonhuman primates. Thoroughly wash your
hands after working with primates and do not eat, drink, or apply
make-up when working with nonhuman primates.
- Cercopithecine herpesvirus 1 (Herpes B) in Macaque monkeys
All macaque monkeys (e.g. rhesus [Macaca mulatta], cynomolgus
[M. fasicularis], pigtail [M. nemestrina]) are potential carriers
of Cercopithecine herpesvirus 1 (Herpesvirus-B, Herpes B, Herpes
simiae, B virus) and should treated as though they are infected
with this virus. This virus is not found in non-macaque species
of monkeys such as the African green, squirrel, or baboon. In
macaques, Herpes B sometimes causes cold sore like lesions but
for the most part there are no obvious problems in the monkey.
Though very rare human infection is usually fatal or produces
severe and lasting neurological disease.
Humans become infected following a bite or scratch, splashes
or contact with tissues, body fluids or excretions, and by injury
from a cage or similar item contaminated with material from an
infected monkey. To prevent potential exposure use personal protective
devices like facemasks, face shields, gloves and long sleeved
laboratory coats. Unless absolutely necessary, never handle an
awake macaque. Use a squeeze cage and a restraint drug such as
ketamine to sedate the primate before handling. Be extremely cautious
when working near the head or close enough for a monkey to grab
you. Treat all monkeys as though they are infected with the Herpes
B virus.
If you receive a bite or scratch wound from a monkey or an injury
from a piece of equipment with which the animal or animal tissues
has had contact, STOP WORK, return the monkey to its cage, institute
first aid immediately. Each primate housing area and laboratory
has been equipped with a "Monkey Injury Kit". Follow
the instructions that are inside the kit. You should familiarize
yourself with them in advance. Following initial first aid, go
to the Occupational Injury Clinic. Notify Animal Services of the
identification number of the monkey and its location so that a
veterinarian can examine the animal and take appropriate steps
to ascertain the potential hazard.
- Experimentally induced infections
Simian Immunodeficiency Virus (SIV) is related to the Human Immunodeficiency
Virus (HIV). This virus does not occur naturally in the primates
currently in use at Johns Hopkins University. Any occurrence of
this virus in a primate at this institution is a result of a deliberate
introduction of the virus into the primate by an investigator.
Such primates are clearly identified.
Individuals working with this virus or monkeys deliberately infected
with the virus must follow guidelines that have been by the Centers
for Disease Control and the University. The guidelines include
working under BSL2 and in some cases BSL3 conditions. In event
of suspected exposure follow procedures described for Cercopithecine
herpesvirus 1 (Herpes B). A prophylaxis protocol will be instituted
through Occupational Injury Clinic following exposure (call 5-STIX)
and anti-retroviral therapy will be offered. It should be noted
that infection of humans with SIV after exposure to infectious
tissues or fluids is extremely unlikely.
Other infectious agents that could be used include measles, vaccinia
virus and Shigella.
- Q-fever
Q fever is caused by the rickettsia, Coxiella burnetti. Domestic
ungulates such as sheep, cattle and goats are reservoirs of infection
for humans and shed the organism in placenta, amniotic fluid,
urine, feces and milk. Infection is acquired by working with these
animals or their products or from laboratories working with C.
burnetti. The illness is generally mild in people, however, hepatitis
is a common sequel and endocarditis is an uncommon but frequently
fatal complication. The disease should be diagnosed and treated
promptly to minimize risk of complications. Currently there are
no approved vaccines.
Chemical Hazards
The Johns Hopkins University Hazard Communication Program gives
employees a means to find information about the hazards associated
with any material in their workplace. Material Safety Data Sheets
(MSDS) are fact sheets that summarize information about the hazards,
handling procedures, emergency first aid and required protective
equipment regarding each substance. Health, Safety and Environment
has MSDS sheets for all substances used at Johns Hopkins. Should
you have a concern or question about any substance in your workplace,
discuss the situation with your supervisor. If the supervisor
is unable to answer your questions, contact Health, Safety and
Environment.
- Labeling
Labeling is an important aspect of the Hazard Communication Program.
All containers must have a label of the common name in English
to identify the contents.
- Cleaning agents
Cleaning agents are a common form of chemical utilized by animal
handlers. All cleaning agents must be stored in labeled and tightly
capped containers at all times. Consult the product label or the
MSDS for appropriate protective equipment when handling cleaning
agents. Always wear a face shield and gloves when handling and
dispensing concentrated cleaners.
- Corrosives and Flammables
Corrosive materials are the most common form of toxic substances
found in a typical laboratory and are frequently used in animal
facilities. These include strong acids, strong bases and oxidizing
agents. When handling corrosive substances ensure that skin, face
and eyes are protected by clothing, laboratory coats, aprons,
eyewear and/or face shields.
Flammable materials are clearly labeled as such on the product
label. All flammable materials not in immediate use should be
stored in an approved flammable materials storage cabinet. Existing
approved cabinets have doors which positively latch. Newly acquired
flammable material storage cabinets must have doors which self-close
and self-latch.
- Evaluate the spill. Are the materials corrosive, flammable,
toxic or explosive
A. Identify all materials by common name.
B. Estimate how much is spilled.
C. Evaluate the degree of danger to patients, staff or visitors.
D. Evaluate the degree of danger to equipment or property.
- Contain the spill.
- If the spill cannot be contained, evacuate the area. Also evacuate
the area if the spill is likely to produce irritating odors, or
flammable or explosive vapors.
- Spills of innocuous material or small amounts of acids, bases
and flammable material can be cleaned up by lab personnel or properly
equipped staff in the area.
- All spills of toxic or explosive materials and large spills
of corrosive or flammable material will be cleaned by Health,
Safety and Environment. Immediately call the emergency number
for your campus.
- East Baltimore Campus 410-955-4444
- Bayview Campus 410-550-2424
- Homewood and other buildings 911
If your skin or eyes are exposed to a chemical, flush the affected
area with large amounts of running water. After on-site first
aid, proceed to the Occupational Injury Clinic for your campus.

Research Registration Programs
In order to control and monitor biological hazards in the work environment,
Johns Hopkins University has established research registration programs
in accordance with federal regulations and guidelines. All research
involving biological agents or materials, sheep, goats, non-human
primates, recombinant DNA, or animals must be properly registered
with designees of Johns Hopkins University Administration.
It is the responsibility of the principal investigator to assure
that individuals working with the registered agents and materials
are appropriately trained and that the protocols are conducted in
compliance with Johns Hopkins University policies.
Registration of Research with HBV,
HIV or SIV
Experimental animal studies involving the use of human HBV or
HIV, suspected HIV, AIDS associated retroviruses or SIV are not
to be initiated without prior approval from the Animal Care and
Use Committee and the Department of Health, Safety and Environment.
Registration of Research with Pathogenic
and/or Oncogenic Material
It is the responsibility of each principal investigator to register
with Health, Safety and Environment all biohazardous agents and
materials presently in use for investigative research and for
all agents maintained in stock culture collections for research
and/or teaching purposes.
Registration of Research with Recombinant
DNA
All principal investigators conducting recombinant DNA research
are required to register such protocols with the Department of
Health, Safety and Environment and the Institutional Biosafety
Committee. Research involving recombinant DNA requires strict
adherence to the most current NIH guidelines.

Part of the emergency response protocols for Johns Hopkins includes
hazard-warning signage. This yellow placard is required to be posted
at the entrances to all laboratories and research areas to indicate
the hazards contained therein. These yellow warning placards must
contain the names and emergency telephone numbers of two individuals
who are familiar with the hazards contained within the area. (Emergency
responders may refuse to enter a placarded area prior to discussing
the hazards contained therein with the emergency contact individuals.)
It is the responsibility of the principal investigator or the area
supervisor to include the emergency contact information on the yellow
placards. If your area does not have the proper warning signage
at its entrances, contact Health, Safety and Environment.
